Angular Material Table Error: Can't bind to 'mdHeaderRowDef' since it isn't a known property of 'md-header-row'

Question

I'm trying to convert a CDK data-table to a Material Design styled data-table (see: https://material.angular.io/components/table/overview), but when I change the cdk prefixes to md, I get the following error...

---

Uncaught Error: Template parse errors: Can't bind to 'mdHeaderRowDef' since it isn't a known property of 'md-header-row'. 1. If 'md-header-row' is an Angular component and it has 'mdHeaderRowDef' input, then verify that it is part of this module. 2. If 'md-header-row' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message. 3. To allow any property add 'NO_ERRORS_SCHEMA' to the '@NgModule.schemas' of this component.

Every answer I've found online tells me that I need to import CdkTableModule, but I have done so & cdk tables work perfectly.

import {Component, OnInit, ViewChild} from '@angular/core';
import {DataSource} from '@angular/cdk';
import { CdkTableModule } from '@angular/cdk';
import { Observable } from 'rxjs/Observable';
import 'rxjs/add/observable/of';
import 'rxjs/add/operator/first';
import 'rxjs/add/operator/startWith';
import 'rxjs/add/operator/catch';
import 'rxjs/add/operator/switchMap';
import 'rxjs/add/observable/merge';
import 'rxjs/add/observable/of';
import 'rxjs/add/observable/interval';
import 'rxjs/add/operator/map';

I am importing CdkTableModule, and when I use the cdk prefix, the table displays as expected...

<md-table [dataSource]="dataSource">

  <ng-container cdkColumnDef="number">
    <md-header-cell *cdkHeaderCellDef> number </md-header-cell>
    <md-cell *cdkCellDef="let element"><a routerLink="{{element.number}}"> {{element.number}} </a></md-cell>
  </ng-container>

  <ng-container cdkColumnDef="book">
    <md-header-cell *cdkHeaderCellDef> book </md-header-cell>
    <md-cell *cdkCellDef="let element"> {{element.book}} </md-cell>
  </ng-container>

  <md-header-row *cdkHeaderRowDef="['number', 'book']"></md-header-row>
  <md-row *cdkRowDef="let row; columns: ['number', 'book']"></md-row>
</md-table>

RESULT: So far so good... but if i change "cdk" to "md"

<md-table [dataSource]="dataSource">

  <ng-container mdColumnDef="number">
    <md-header-cell *mdHeaderCellDef> number </md-header-cell>
    <md-cell *mdCellDef="let element"><a routerLink="{{element.number}}"> {{element.number}} </a></md-cell>
  </ng-container>

  <ng-container mdColumnDef="book">
    <md-header-cell *mdHeaderCellDef> book </md-header-cell>
    <md-cell *mdCellDef="let element"> {{element.book}} </md-cell>
  </ng-container>

  <md-header-row *mdHeaderRowDef="['number', 'book']"></md-header-row>
  <md-row *mdRowDef="let row; columns: ['number', 'book']"></md-row>
</md-table>

RESULT: Broken :(

I've tried importing other modules... including MdTableModule & MdTable, but that hasn't proven helpful either. Any ideas?

P.S. Here's my main app.module.ts import statement in case that helps

imports: [
BrowserModule,
FormsModule,
HttpModule,
AppRoutingModule,
ReactiveFormsModule,
BrowserAnimationsModule,
MdAutocompleteModule,
MdButtonModule,
MdButtonToggleModule,
MdCardModule,
MdCheckboxModule,
MdChipsModule,
MdTableModule,
MdDatepickerModule,
MdDialogModule,
MdExpansionModule,
MdGridListModule,
MdIconModule,
MdInputModule,
MdListModule,
MdMenuModule,
MdCoreModule,
MdPaginatorModule,
MdProgressBarModule,
MdProgressSpinnerModule,
MdRadioModule,
MdRippleModule,
MdSelectModule,
MdSidenavModule,
MdSlideToggleModule,
MdSliderModule,
MdSnackBarModule,
MdSortModule,
MdTabsModule,
MdToolbarModule,
MdTooltipModule,
MdNativeDateModule,
CdkTableModule,
StyleModule
 ]

Which version of material? – Magnanimous

I figured it out! – Chromoplast

I updated to "@angular/material": "^2.0.0-beta.10" and changed the DataSource import to: import {DataSource} from '@angular/cdk/table' and the CdkTableModule import to: import { CdkTableModule} from '@angular/cdk/table' ... and alas it works! – Chromoplast

Answer 1

After another hour of fiddling with things, I ran

npm update --save

and updated @angular/cdk and @angular/material to 2.0.0-beta.10

in package.json

 "@angular/material": "^2.0.0-beta.10",
 "@angular/cdk": "^2.0.0-beta.10",

This broke some things, so I had to dig around and needed to update imports of DataSource and CdkTableModule

       import { CdkTableModule} from '@angular/cdk/table';
       import {DataSource} from '@angular/cdk/table';

component.html

 <md-table [dataSource]="dataSource">

    <ng-container mdColumnDef="number">
      <md-header-cell *mdHeaderCellDef> number </md-header-cell>
      <md-cell *mdCellDef="let element"><a routerLink="{{element.number}}"> {{element.number}} </a></md-cell>
    </ng-container>

    <ng-container mdColumnDef="book">
      <md-header-cell *mdHeaderCellDef> book </md-header-cell>
      <md-cell *mdCellDef="let element"> {{element.book}} </md-cell>
    </ng-container>

    <ng-container mdColumnDef="s1">
      <md-header-cell *mdHeaderCellDef> S1 </md-header-cell>
      <md-cell *mdCellDef="let element"> {{element.sections[0] ? element.sections[0].type : ''}} {{element.sections[0] && element.sections[0].qs ? '('+element.sections[0].qs.length+')' : ''}}</md-cell>
    </ng-container>

    <ng-container mdColumnDef="s2">
      <md-header-cell *mdHeaderCellDef> S2 </md-header-cell>
      <md-cell *mdCellDef="let element"> {{element.sections[1] ? element.sections[1].type : ''}} {{element.sections[1] && element.sections[1].qs  ? '('+element.sections[1].qs.length+')' : ''}} </md-cell>
    </ng-container>

    <ng-container mdColumnDef="s3">
      <md-header-cell *mdHeaderCellDef> S3 </md-header-cell>
      <md-cell *mdCellDef="let element"> {{element.sections[2] ? element.sections[2].type : ''}} {{element.sections[2] && element.sections[2].qs ? '('+element.sections[2].qs.length+')' : ''}}</md-cell>
    </ng-container>

    <ng-container mdColumnDef="s4">
      <md-header-cell *mdHeaderCellDef> S4 </md-header-cell>
      <md-cell *mdCellDef="let element"> {{element.sections[3] ? element.sections[3].type : ''}} {{element.sections[3] && element.sections[3].qs ? '('+element.sections[3].qs.length+')' : ''}}</md-cell>
    </ng-container>

    <md-header-row *mdHeaderRowDef="['number', 'book', 's1', 's2', 's3', 's4']"></md-header-row>
    <md-row *mdRowDef="let row; columns: ['number', 'book', 's1', 's2', 's3', 's4']"></md-row>
  </md-table>

component.ts

 import {Component, OnInit} from '@angular/core';

 // Data Table imports.
     import { DataSource } from '@angular/cdk/table';
     import { Observable } from 'rxjs/Observable';
     import 'rxjs/add/observable/of';

 @Component({
   selector: 'app-start',
   templateUrl: './start.component.html',
   styleUrls: ['./start.component.css']
 })
 export class StartComponent implements OnInit {

   pts: Pt[];
   dataSource = new ExampleDataSource(this.ptService);
   constructor( public ptService: PtService ) { }
   ngOnInit() {
     this.pt = this.ptService.getPts();
   }
 }

 export class ExampleDataSource extends DataSource<any> {
   data = this.ptService.getPts();
   constructor( public ptService: PtService ) { super() }
   /** Connect function called by the table to retrieve one stream containing the data to render. */
   connect(): Observable<Pt[]> {
     return Observable.of(this.data);
   }
   disconnect() {}
 }

Phew!

Answer 2

import MatTableModule in app.module.ts

import { MatTableModule } from '@angular/material/table';

@NgModule({
  imports: [
     MatTableModule
  ]
})
export class AppModule { }

Answer 3

Since "^2.0.0-beta.11" all the selectors that start with md are not valid and should be replaced with mat so you have to replace all of them, in material website the documents do not seem to be updated yet.

All types of tables have her own prefix if you use one type you have to use her prefix. It's clear like that
